services: add standalone bootstrap to sky-cam, sync-cc, traccar, unifi, uptimekuma, vaultwarden

Each service can now be run directly with sudo bash <service>.sh on any
machine with Docker installed, without needing the full post-install repo.
Uses the shared bootstrap pattern from docs/standalone-template.sh.
